Hi Satyakki,
What a portrait and what eyes too. From the thumbnail, this mans eyes grab your attention instantly. The background has a slightly surreal feeling with how you have positioned the tree, and eye lighting, and this suits the subject perfectly.
BlAck and white is a beautiful choice..
Thanks for the excellent informative note too, a pleasure to see this photo.
All the best
Noel

A most intense figure here, Satyakki - the B&W treatment serves him well not just for a sense of seriousness but also for the excellent contrast it brings to his beard and to the surroundings. An unusual portrait pose as well, staring straight ahead into the lens - almost confrontational, except that we know who he is! Nice work.
